Jeez! A bloke spends a few days away with his Jaffa cakes and returns to carnage!! I got this lot from Farnell in the summer, waiting for the cold weather. The part numbers work, * means I had some in a bucket somewhere. And the formatting's crap. Sorry a bit better now :beer:.

I created a component list with Mouser a couple of weeks ago.. Total cost of everything except PCB is approx $US43 - plus shipping. I don't know if Mouser is an option for UK based purchase but I can share the project file if anyone is interested. I can do the same with Digikey if there's interest. Update: $23 of that cost was for a 20x4 LCD. You can pick these up from a number of online sources for $10 - $12 As far as PCB go, I use pcbcart.com which is a Chinese based manufacturer. Prices are pretty good e.g. 20 off 100mm x 150mm double sided boards, silk screen cost $US144. Turn around of 12 days. Artwork must be provided as Gerber files. There are also a couple of places that specialise in prototyping boards i.e. 10 boards, 100mm x 100mm double sided $US28 plus shipping. Add an extra $US10 if you want blue boards. ::) I haven't checked the size of the driver board so don't know how useful this information is. |

I am not happy with direction this started to take. I am glad to see that it has gotten back on track. So let's cool the hostilities. We are all adults here. This is Jason's thread... I am removing the posts that do not add to this thread. Eric |

--- Quote from: John Stevenson on November 25, 2010, 06:27:16 PM ---Bogs, If you are willing to use an old laptop or desktop computer I can supply everything except the table. It will be a box with mains plug on, USB plug for the computer and a lead out going to a stepper motor. You start the computer, start the program and this is what you see. Does basically all a Division master does but not hand held. John S. PS Send photo of hairy arse. --- End quote --- Last line of this looks a bit .. er ... surreal now Eric :lol: Dave BC |
